Which of the following represents a reflex angle?

Option 4 : (iii) only

An acute angle measures between 0° and 90°, whereas a right angle is exactly equal to 90°.

An angle greater than 90° but less than 180° is called an obtuse angle. Also, recall that a straight angle is equal to 180°.

An angle that is greater than 180° but less than 360° is called a reflex angle.

Further, two angles whose sum is 90° are called complementary angles, and two angles whose sum is 180° are called supplementary angles.
